RECEPTACLE FOR GRANULAR SUBSTANCES.

SPECIFICATION forming part of Letters Patent N0.460,181, dated September 29, 1891.

Y Application filed January 7, 1891. Serial No. 376,953- (No modell) To all whom it may concern.-

Be it known that I, BENJAMIN F. PITEZEL, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Receptacles for Granular Substances, of which the following' is a specification.

This ineution relates to improvements in receptacles for granular substances, but is more especially designed as a coal-box for domestic purposes, and has for its prime object to provide a receptacle of novel construction combining in the maximum degree convenience andutility, as well as economy of the commodity contained therein.

Another object is to have the receptacle of such construction that the door for opening and cutting off the discharge will be easy of manipulation, will be relieved of the weight of the contained commodity, and maybelocked against surreptitious openin g or unwarranted tampering therewith.Y

Other objects are to have the receptacle capable of equally successful use with granular and similar substances varying materially in size, to collect and retain the dust from such substances, and thereby prevent its discharge horizontal section thereof; Fig. 3, a detail perwith a double wall at the front side thereof by the addition of the partition A, between which and the front wall B there is sufiicient space to contain most of the operative parts of myinvention, the receptacle being divided into two compartments C D by means of an `oblique or inclined partition E about the centacle and subserving the further purpose of a top or roof for the compartment D, to which access is gained through a door F in the sides of the receptacle, and in which compartment wood or any other material may be stored.

In the front double wall, connecting the wall A B and extending a suitable distance beyond the latter for convenience, is a chute G, the bottom of which is flush with the partition E and inclined at the saine angle as said partition, so as to constitute a continuation thereof. This chute is provided with an external gravity-door H, covering the discharge end thereof 'and preferably hinged thereto along its upper edge, so that the discharging substances will swing the door open, and it will close by gravity, thus avoiding the necessity for manipulating the same by hand.

In suitable guides I, (see Fig. 2,) secured between the walls A B, works a sliding door J, provided with a central squared aperture K, conforming in shape and dimensions with the cross-section of the chute, which latter is divided into two sections between which the door slides, as clearly illustrated in Fig. .5, there being sufficient room betweenthe edge L of the inner section of the chute andthe door to permit dust and other fine particles from the commodity contained in the receptacle to fall down between the wallsA B into Aa dust-drawer M in the lower part of the receptacle. This door is counterbalan ced by a pair of Weights N, attached to cords O, working over pulleys P in the upper part ot the receptacle and attached at their opposite ends to the upper edge of the door, which latter is also provided with a handle Q-near the upper end thereof, projecting and working through a slot R in the Jfront wall of the receptacle for convenience of manipulation.

To prevent surreptitious opening of the door, a lock of any suitable nature may be IOO provided, such as the lock S, (illustrated in Fig. 6,) the key to which will be retained in possession'of the user of the receptacle.

Within the upper compartment C, and adapted and arranged to partially or Wholly close the chute G, is an adjustable gate T, of substantially the dimensions as the chute or slightly greater, which is secured to the lower end of a rod U, lying along the inner side of the partition A and projecting up through a suitable opening in the hinged top or cover V of the receptacle, where it may be secured at any desirable point of its adjustment by some suitable locking device, such as set screw W, (illustrated in the drawings.) This gate in practice is designed to be adjusted over the mouth of the chute to an extent corresponding with the nature of the material contained in the receptable to be discharged through the chute, leaving a less opening at the mouth of the chute for the smaller materials and a correspondingly larger opening for the larger materials, av familiar example of which use for household purposes is that of chestnut'coal for some purposes and small or large egg coal for other purposes. By the employment of this gate the door is practically relieved of the entire weight yof the body of the material contained in the receptacle and renders the opening and closing of the door a very easy matter, while it would be an extremely difficult matter, as practice has demonstrated, without the employment of this gate. For convenience inopening the receptacle for reilling, the entire top of the receptacle, or the front half thereof, as shown, may be hinged for vthe purpose of gaining access to the interior of the receptacle or for refilling the same, at which time the gate, with its carrying-rod, will be dropped down sufficiently to permit the swinging of the top on its hinges, leaving the gate in the box.

In practice, supposing the receptacle to be in domestic use and filled with coal, some of which it is desired to remove, the scuttle will be placed under the chute and the door unlocked and depressed until the aperture K therein registers with the chute, when the coal will pass therethrough into the scuttle until the latter is filled, when by pulling up on the handle Q the supply may be easily and quickly cut off by returning the door to its elevated position with the lower solid portion thereof spanning the chute and the aperture therein above the chute.

It will be noted, as before stated, that by the interposition of the gate T the door is relieved of practically all of the weight of the coal in the box, and that as the door closes by lifting, and the little coal above the door is free to be raised thereby, very slight effort is required to close the door, and all danger of clogging the action of the door by the jamming between it and the chute of lumps of coal is avoided, which would not be the case without the employmentof the gate, and which result is especially facilitated by the upward i11- stead of downward movement of thedoor in closing.

Such a receptacle as is herein shown and described is of great utility and convenience for containing any kind of granular or similar substance, but is of especial convenience and utility for domestic purposes to dwellers in flat-buildings, in which the supply of fuel is allnost invariably and frequently of necessity contained in a box or bin upon the back porch, where the family washing must be dried and where the presence of dust occasioned by getting out coal from such boxes as ordinarily constructed is particularly objectionable and injurious, aside from the ordinary desire for cleanliness, besides which such porches are easy of access from the rear and are subject to the designs of thieving and malicious persons.

While l have shown and described the use of the gate T in connection with the vertically-sliding door and prefer the use thereof for reasons hereinbefore set forth, at the same time it would not be a departure from the spirit of my invention to omit the gate, for by reason of the casing-in of the door, so as to expose but little surface to the action of the coal contained in the chutes, in conjunction with the vertical action ofthe door in opening and closing for granular substances such a construction would be all sufficient, because by such construction the door is practically relieved from most of the weight of the substance contained in the box and moves in such direction as to best overcome the weight and at the expenditure of the least power.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-
